Anaerobic versus aerobic exercise programsThere are two types of exercise: Anaerobic and Aerobic. The word anaerobic refers to exercise without air or oxygen. Anaerobic exercise involves using isolated muscles at high intensity and a high rate of energy for a short duration. Anaerobic exercise is less stressful on your joints because movement is more intense over a short time span. Aerobic exercise is also referred to as cardiovascular exercise. It involves using oxygen for low intensity exercise over a period of time, turning fat into fuel. It is more stressful on the joints than anaerobic exercise because movement is repetitive over a longer time span. A balanced fitness program includes both aerobic and anaerobic exercise. Anaerobic Exercise Anaerobic exercise is sometimes referred to as non-aerobic exercise or strength and is typified by weight training. It includes weight lifting, sprints, throwing or any rapid burst of hard exercise. Anaerobic exercise uses the phosphagen system of respiration, which utilizes ATP, the chemical required by muscles to contract. The body can sustain a maximum effort for only about 10 seconds before the ATP is depleted and lactic acid is produced. High intensity exercises of longer duration utilize glycogen in the muscles as their energy source and form lactic acid as a waste product. With training, exercises can be done at about 90 per cent efficiency for a maximum of two or three minutes. After this, the muscles become fatigued through the build up of lactic acid. The body must burn this up before more anaerobic exercise can be done. Aerobic Exercise Major Kenneth Cooper of the US Air Force coined the phrase aerobic exercise. American astronauts developed it in the 1960s for use during space travel. In the 1990s, low impact aerobics was introduced in health clubs – a great way to burn calories and improve body shape.
Aerobic exercise enhances the cardiovascular system, improving the flow of oxygen throughout the body. As oxygen-rich red blood cells circulate through the body, the muscles are able to use the oxygen to breakdown glucose and convert it into energy. Any activity that raises the heart rate and keeps it up for an extended period of time will improve aerobic fitness, these activities may include: healthy eating plan and a healthy lifestyle, you will be well on your way to self-confidence and a great body.
